5. Markets 06 May 2011 5 Selected Results (1)  Received over 30 detailed responses for technical measures, covering all categories of technical measures in scope.  For some technical measures it is possible to conclude market status without much external consultation (for example the quantity of suppliers in a particular area tells us a lot about the market / market share).  Additional information (for example Network Statements) provide some information on installed base for some technical measures.
